MORRIS lV. MOORE, OF SPRINGFIELD,

MASSACHUSETTS, ASSIGNOR TO FRED- FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 435,900, datedSeptember 2, 1890.

Application tiled April 18, 1890.

To all whom it may concern.:

Be it known that I, MORRIS W. MOORE, a citizen of theUnited States,residing at Springfield, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements inFountain-Pens, of which the following is a specification.

- This invention relates to fountaimpens, the

object being to provide a pen of this class of 1o improved constructionin relation to means for controlling the iiowof ink from the reservoirto the pen; and the invention consists in the peculiar construction andarrangement of the pen-supporting and ink-feeding parts of the pen, allas hereinafter fully described and pointed out in the claim.

In the drawings forming a part of this speci- Ication, Figure l is aside elevation, partly in section, of a fountain-pen constructed accord-2o ing to my invention. Fig. 2 is a longitudinal sectional view of thelower portion of the pen, excepting the feed-bar thereof, which is notshown in section. Fig. 3 is a transverse section on line 3 3, Fig. l. Fi4 is atransverse section on line 4.4., Fig. l. Fig. 5 is a perspectiveview of the cylindrical pen-holding spring. Fig. G is a perspective viewof the valve which controls the ow of ink from the reservoir.'

In the drawings, 2 indicates the reservoir 3o of the pen, constructed,preferably, of hard rubber or similar non-corrosive material, and havingits upper end hermetically closed and its opposite end open andinternally screwthreaded, as shown. The tip 3 of the pen- 3 5 fountain,also preferably made of hard rubber, is screwed into the lower end ofthe said fountain 2, as shown in Figs. 1 and 2, and is thus madeconveniently removable from the open end of the fountain, for thepurpose of 4o filling the latter with ink B, and of adj Listing theparts of the pen, as below described, which control the flow of ink fromthe fountain to the tip of the pen proper 4. The said tip 3 has acylindrical longitudinal passage through it from end to end, saidpassage beingindicated by a, and said passage c in its upper portion, orthat which is within the end of the fountain 2 when the parts areassembled, as in Figs. l and 2, is of less diameter than that portion ofSerial No. 348,577. (No model.)

said passage below the end of the said fount- 5o ain. The said upper endof the passage through the tip 8 is made, as aforesaid, of a smallerdiameter than the lower end thereof to adapt it to the diameter of theshank of the ink-feeding bar 5, said shank being adapted to iit fairlyeasy in said passage and to be movable endwise therein for the purposeof adjusting its outer end or point to a proper position relative to thepoint of the pen proper e. The said upper and smaller portion of the 6opassage d through the tip 3 has formed in the walls thereof one or morelongitudinal grooves c, which serve to convey ink from the reservoirthrough the upper end of the tip 3 into the lower enlarged portion ofthe passage a in said tip, and thence along the sides of the feed-baroto the point thereof, and thence to the pen 4. The said grooves c in theWalls of the passage through the tip 3 serve as ainple conduits for theink B, which must neces- 7c sarily flow unobstructedly to the pen 4; butit is obvious that without proper means for controlling the Iiow of inkthrough said con duits c (and said conduits must be of suita ble depthto prevent them from heilig clogged by thick ink) an oversupply of inkwould be delivered at the point of the pen 4, and hence there isprovided on the inner end of the shank of the pen-bar 5 an adjustablecylindrical valve G, which may be made of any 8o suitable material; butrubber is the preferable one. Said cylindrical valve Gis movable up anddown on the shank of said pen-bar opposite the inner end of the tip 3 ofthe pen, and said valve is of such diameter or S5 thickness beyond thesides of said feed-bar shank as provides for covering the upper ends ofthe said feed grooves or conduits c in the inner walls of the tip 3,which adjoin the sides of said feed-bar shank, so that if 9o said valveG be moved on said shank down against the upper end of said tip 3 theink passages or conduits c would be entirely closed and no ink wouldiiow therethrough, and to secure the proper iiow of ink from thereservoir through said passages, as aforesaid, to the pen 4 the saidvalve is adjusted to such position above or away from the adjoiningupper end of the tip 3 as may be necessary to permit the ink, should itpossess more or less fluidity, to flow in proper regular quantitiesthrough said conduits c. The lower or enlarged portion of the passage oathrough the tip 3 is adapted to receive therein thecylindricalJpen-holding spring 7, and said spring serves to hold firmlythe shank e of the pen 4 When the latter is forced into said passage a,between the Wall thereof and said spring 7, the latter being made,preferably, of sheet metal, and is held tightly in the lower end of thetip 3 by'frictional engagement therewith. The ink-feeding bar 5 extendsthrough said spring 7, as shown in the drawings.

The usual cap, which protects the pen 4 and adjoining parts when thedeviceis not in use or arranged to be carried in the pocket, isindicated by D, the upper end of the fountain 2 being of suitablereduced size, as shown, to receive and hold said cap thereontemporarily.

The parts of the pen are shown in the drawings as considerably enlarged,in order to more clearly illustrate their construction and relations. v

What I claim as my invention is-n In a fountain-pen, a tip thereforhaving a passage therethrough to receive the ink-feeding bar, and havingone or more inkconduct ing grooves inn thewalls thereof, combined withsaid feeding-bar, a valve movable on said bar toward and from theends ofsaid grooves,

and an ink-reservoir connected with said tip,l

substantially as set forth.
